The financing included four new investors and was led by Susquehanna Growth Equity (SGE), a US-based private equity fund. SGE was joined by European-based Advent Venture Partners, Bridge Capital Fund of Japan, and Yasuda Ventures. Existing Wisair investors also participated, and included Apax Partners, Broadcom, Intel Capital, Vertex, and Zisapel brothers from the RAD group.

The addittional funding will be used to accelerate the release of products with integrated WUSB capabilities to satisfy the burgeoning demand for simple high-speed wireless connectivity in the consumer electronics industry, the company said.

Last year, Wisair said it can deliver 100 Mbits/ second of application-level throughput with its WSR601 chip when used as an external USB plug-in device and 300 Mbits/s when integrated natively into a system. The 130-nm chip consumes 250 mW average and 600mW peak and will sell as a full module for under $15.
